Choosing a size

Which barndominium size is right for you?

Start with how much shop you need, not just how much house. The most popular configuration we build is the 40×60 — roughly 1,200–1,400 sq ft of living plus a real two-bay shop — because it fits a complete home and a working shop in one envelope. Going smaller (30×40, 30×50) keeps it to a compact home or a home with a single bay; going larger (50×80 and up) buys serious shop space, more bedrooms, or commercial-grade working room.

How much does each barndominium size cost?

Turnkey starts at $115 per square foot of total footprint and runs to about $200 all-in, depending on finish level and your site. “From” prices below are the entry of that band for each footprint — a complete, finished, move-in build managed through our contractor network. A bare shell kit runs about $28 per square foot if you’re building yourself.

“From” prices = $115/sqft (national turnkey entry rate) × footprint, the same basis the individual size pages use. Verify against current rates before publish.

Custom, not catalog

Every size is a starting point — not a stock plan.

The footprints here are the most-requested envelopes, but they aren’t the whole menu — and we don’t sell fixed floor plans off a shelf. Each build is drawn from scratch around your life: where the bedrooms go, how much of the box is living versus shop, sidewall height, door count, finish level. Pick a footprint that fits your land and budget — or tell us yours — and we design the plan that fits you.

Common questions

Size questions buyers ask first

What’s the most popular barndominium size?

The 40×60 is our most-requested footprint. At 2,400 sq ft it fits a complete 2–3 bedroom home plus a real two-bay shop in one envelope — the classic shop-house, and the size that defines the category for most buyers.

How much does a barndominium cost?

Turnkey runs $115–200 per square foot of footprint, all-in, depending on finish and site — so a 40×60 starts around $276,000 and a 30×40 around $138,000. A bare shell kit is about $28/sqft if you build it yourself. Each size page and the cost hub break it down further.

What size barndominium do I need?

Size it by use, not just square footage. A couple or downsizer is comfortable in a 30×40 or 30×50; a family wanting a home plus working shop fits the 40×60 or 40×80; homesteaders and home-based businesses move to 50×80, 50×100, or the 60×100 live-work building. The “best for” column above is the quickest filter.

Can I change the layout?

Yes — that’s the point. We design every plan custom, so the living-to-shop split, bedroom count, ceiling height, door spec, and finish are all yours to set. The footprints are standard; the plan inside them never is.
